In addition, by operating the power key 64, an on state and an off state of a first battery unit 60 and a second battery unit 62 described later can be switched as appropriate.

  The control circuit 36 is connected to an illumination unit 46 having a predetermined color LED element. The display 42 is given a predetermined color by the light emitted from the LED elements of the illumination unit 46.

  Next, the operation of the cellular phone device 10 according to the present embodiment will be described.

  2 and 3 are flowcharts showing the operation of the apparatus of this embodiment.

  FIG. 2 is a flowchart for registering the time and destination for transmitting position information.

  In step S <b> 1, the control circuit 36 inputs information on the time (transmission start time or transmission start time and transmission end time) at which the mail with the location information is transmitted from the input unit 44 and stores it in the RAM 40.

  In the subsequent step S2, the control circuit 36 inputs the information on the mail address of the other party (for example, the user's mother) to send the mail from the input unit 44, and stores it in the RAM 40 in association with the transmission time in the above step S1. .

  In subsequent step S3, the control circuit 36 inputs a mail title (for example, help) from the input unit 44, and stores it in the RAM 40 in association with the transmission time in step S1.

  In the subsequent step S4, the control circuit 36 inputs a time interval (for example, every 2 minutes) for transmitting the mail from the input unit 44, and stores it in the RAM 40 in association with the transmission time in the step S1. Registration is thus completed.

  Next, the mail transmission operation will be described. FIG. 3 is a flowchart for explaining mail transmission.

  If the control circuit 36 determines in step S10 of FIG. 3 that the transmission start time stored in the RAM 40 has come, the process proceeds to step S11.

  In step S11, the control circuit 36 sets the display 42 in a standby display (for example, a wallpaper registered in advance by the user, the current time, a battery mark, an antenna mark, etc.) and advances the process to step S12.

  In step S <b> 12, the control circuit 36 receives the current position information by controlling the GPS communication unit 58.

  In the subsequent step S13, the control circuit 36 attaches and transmits the position information received in step S12 to the other party stored in the RAM. In addition, a timer (not shown) is started after mail transmission. This timer is a timer for measuring a time interval for automatically transmitting mail stored in the RAM 40. In a normal mobile phone device, when mail transmission is started, a message indicating that the mail is being transmitted is displayed on the display, such as during mail transmission. The display of does not change.

  If the control circuit 36 determines in step S14 that there is a key operation from the input unit 44, the process proceeds to step S15, and if not, the process proceeds to step S16.

  In step S15, the control circuit 36 causes the display 42 to display that charging is required. Note that in this step S15, it is displayed that charging is required, for example, when the criminal performs a key operation, he / she thinks that the mobile phone cannot be used, and hinders automatic transmission of an e-mail with location information attached. In this case, the battery mark displayed on the display may be switched to a battery mark indicating that the remaining amount is low. Further, in addition to displaying “required charging”, a screen prompting the user to input a password may be displayed.

  In the subsequent step S16, when the control circuit 36 determines that the timer started in step S13 has counted the predetermined time stored in the RAM 40, the control circuit 36 resets the timer and then returns to step S12. Then, the process proceeds to step S17.

  In step S17, if the control circuit 36 determines that the predetermined time (mail transmission end time) stored in the RAM 40 has come, the process ends. If not, the process proceeds to step S14. In addition, when the mail transmission end time is not stored in the RAM 40, it is possible to continue to transmit the mail with the location information attached repeatedly every predetermined time unless the user performs a predetermined operation.

  In this way, in this embodiment device, if there is a key operation when automatically sending an e-mail with location information attached, it is displayed on the display section that you need to charge or enter a PIN, so for example, Therefore, it is not realized that the location information is transmitted to the kidnapper, and the function as a crime prevention of the mobile phone device can be effectively utilized. Further, when a key operation is performed, the display of the standby screen may be maintained or the screen may not be switched. Thereby, it is possible to make the criminal think that the mobile phone is broken and cannot be used.

  In order to inform the user (for example, a child) whether or not the position information is automatically transmitted, the display screen is changed to a specific screen (for example, a panda image) when it is time to transmit the position information. It may be displayed.

  In this embodiment, the mail is sent during a predetermined time. However, the mail may be sent according to the user's key operation. In such a configuration, for example, when a child is kidnapped, the child can perform a key operation and immediately send an email.

  Furthermore, this embodiment prohibits the display of a message such as sending a mail, but a message such as "Press ... to start sending" or "Sending has finished". May be prohibited from being displayed.

  In the present embodiment, the configuration in which the position information is attached to the mail and transmitted is described. However, only the position information may be transmitted.
